TRACTOR enuncia. confrnon- Beit known.that,fI,= -CLARnNon-D. METZ- Gnn,.a-citizen of th'GQUnited States, residing at Shelby, in the county ofR1chland and State of Ohio, have invented certain new andusefulImprovements ing-Tractor. Clutch Controls; and I do declare thefollowing 'to be a full, clear, and exact description of the invention,suchaswill enable'fothers skilled in the artto which it and use thesame.

My invention relates to improvements in devices for holding the clutchesof tractors in an inoperative position. I am aware that numerous deviceshave heretofore been provided for this purpose, but my invention aims toprovide a generally improved construction which, although being simpleand inexpensive, and easy to attach, will be highly desirable and willnot interfere with proper operation of the tractor when the driver issitting upon the seat.

v With the foregoing in view, the invention resides in thevnovel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawing.

i Fig. 1 is a side elevation of my invention attached to a Fordsontractor.

FigjQ is a rear edge view of the attachment.

Fig. 3 is an enlarged fragmentary side elevation.

Fig. 4 is a detail vertical section as indicated b v linea-4 of Fig 3.

Figi 5 is va side elevation looking inthe opposite direction from Fig.2, partlyin vertical section.

In the drawings above briefly described, the numerals 1 designate a pairof collars eachI of which Vis divided into upper and lower halvesadapted to be clampedr together around the rear axle, of the tractor, byappropriate'bolts 2. collarsl and the lower halves thereof are connectedrespectively nby integral webs 3, through which the bolts 2 may pass.The upper sides of the upper collar halves are provided with flat facedseats 4 and the horivzontall foot 5 of an upstanding segmental rack 6,is secured upon said seats by cap screws yor the like 7. The rack 6 isprovided with a stationary or permanent stop 8` with a removable stop 9,and with a lateral stud edgeof said rack." v i A castingll*` is formedwith an opening 12 appertains to make this guide being provided with'aThe upper halves of the 10, .this studbeing 1 concentric the kcurvedreceiving. the stud 10- and lthis castingxis formedin one"vl side"withan angular groove 12S. This groove'receivesxthe lower end of .anupstanding hand lever-111 andl the rear end' of an armf1-5 whichis'integralwith and f extendsV forwardly fromisaid lowerxend'A of thelever, the connecting portion v of said lever and arm being secured inthe groove 13 by bolts or the likevl. This construction is vsimple `andinexpensive, yet is very f strong and eliicient. v

The lever 14 is provided with a dog 17 lfor engagement withy either lofav pair of notches 18 in the segmental rack 6 and numeral 19 designatesa guide forsaid dog,

depending lug 20 which engages the side of the rack 6 opposite saidstud, thereby holding the lever and the casting 11' against lateralmovement from engagement with said stud, until'the removable stop 9,which is preferably in the form of a cotter pin, iswithdr'awn and thelever is swung entirely clear of the rack. When this-is from the stud,but otherwise is held against such movement. 4

In applying the invention, the collars 1 are clamped upon the rear axlelof thetractor andV after being turned thereonto properly associate thearm 15 with the clutch pedal, set screwsQlwhic'h pass through one orboth Y of said collars, are tightened, thereby positively holding thecollars against further` rotation.V through the instrumentality ofanysuitable hand piece such `as 22, the'leverld may be operated todepressthe clutch pedal, whereupon engagement of the .dog 17 with theforemost of the notches 18 willhold said i done, the lever may-be movedclutchpedal in this depressedposition, with i" the clutch out. `Thisholds the tractorl out of gear. which is'not only of advantage whenusing the usual belt drivingpulley 'of the machine, but when the" drivermust stop and leave the tractor for any reason. When this is requiredit'is now customary to throw the gear shifting lever into neutral, butby the 1" use of my invention, this is'not necessary.-v

Excellent `results have been obtainedfrom the details disclosed and Ithereforek prefer to follow such details. However, it is to be 9o.v Bynowreleasing the dog 17, I

understood that Within the scope of the invention as claimed, numerousminor Changes maybe made.

I elaine: 1. A clutch control for tractors comprising a pair of spacedoollarseaoh formed of d .said raok iandliavinga dog-engaging the saine,and Vva rigid. clutch 'operating .=arm.extending lforwardly from' saidflever.

2. A clutch control:fon-tractors*eomprising l aY casting yadaptedto betuloru-ined. on

tractor :said Casting "having van angular groove in one side, la l:handlever havinga clutch operating arm at an angle to its lower end, theconnecting portion of said lever and arm Ming snug-ly reeetved in saidangular groove, and .means securingsa'idlconnecting @P Oltlon to saidcasting.

:3. A clutch. control comprising a segmental raolt having a permanentstop at one lend, a removable stop at its other end, and a lateral studconcentric With the curved hack/edge,:andfaylever having an openingreceiving said stud and a lug engaging the side of therackzoppositefsaid'stud, whereby to 'holdtheblever against vmovementfrom the stud `until-said jremovable stop Ais removed and theleverLswung to disen.gage-said lug rfrelnf the rack.
